Abstract:
A low voltage drive circuit (LVDC) includes a digital to digital converter that converts transmit digital data into a digital input signal, wherein the transmit digital data is synchronized to a clock rate of a host device and the digital input signal is synchronized to a clock rate of a bus to which the LVDC is coupled. An output limited digital to analog is converter converts the digital input signal into analog outbound data by generating a DC component and converting the digital input signal into an oscillating component at a first frequency, wherein magnitude of the oscillating component is limited to a range that is less than a difference between magnitudes of power supply rails of the LVDS, and wherein the oscillating component and the DC component are combined to produce the analog outbound data. A drive sense circuit conveys the analog outbound data as variances in loading of the bus at the first frequency and wherein analog inbound data is represented within an analog receive signal as variances in loading of the bus at a second frequency.
